Treatment results
All initial treatment objectives were achieved with a well-aligned dentition, closure of all the diastemas, good occlusion, and improved facial aesthetics.
The whole treatment was achieved by retraction of both upper and lower lips, resulting in a passive lip seal and relatively straight profile after treatment. Good root parallelism was achieved with minimal root resorption. There was an improvement in the incisor inclination and soft tissue profile, particularly across the E-line and the nasolabial angle (Igure 4c, 4d).
